What action should the nurse take prior to a CT scan with IV contrast?

The most appropriate action for the nurse to take prior to a CT scan with IV contrast is to advise the client that they may experience a flushing sensation during the exam. This sensation is typically caused by the rapid infusion of the contrast material, which can lead to warmth and a feeling of flushing throughout the body. Informing the client about this potential experience helps to alleviate anxiety and prepares them for what to expect during the procedure, ultimately enhancing their comfort and cooperation.

While other options might be relevant in different contexts or scenarios, they do not specifically address the immediate experience related to the administration of IV contrast during a CT scan. For instance, removing medicated patches may not be necessary if the substance is not contraindicated with the contrast. Instructing the client to empty their bladder is generally a standard practice before many imaging exams, but it is not specific to the use of IV contrast in a CT scan. Collecting data about an implantable pacemaker is important in some contexts, but that aspect is more about safety and contrast used rather than addressing the experience related to the contrast infusion itself.
